Greetings,
The spearfish sample data includes raw map data subdirectories ('dlg'
for USGS data, and 'TIGER' for census data) within the PERMANENT mapset,
which seems like a good place to store raw map data. I'd like to setup
a location directory to do the same thing. However it doesn't appear
that any of the g.* commands can make a directory, and the GRASS
documentation warns against manually manipulating the data directory.
I'm hoping someone will direct me to a reference (or a source code file)
that describes what manual directory manipulation is allowed and what
isn't ... I suppose the reason for disallowance would be nice to know
also.
Regards,
Greg

It isn't. The dlg directory is there because that's where v.in.dlg and
v.out.dlg expect the DLG files to live. That was a mistake on the part
of whoever wrote those programs.

Creating additional[1] directories within the mapset directory should
be harmless, but isn't recommended. The main thing to avoid doing is
modifying or deleting any file or directory which is "known" to GRASS.
[1] I.e. directories which don't have any significance to GRASS.
